Flood risk in L14 (Liverpool)
Of the 479 postcodes in L14 – covering Liverpool and Huyton with Roby – none has its centre in Flood Zone 2 or 3 on the Environment Agency’s Flood Map for Planning. River and sea flood risk across the district is low.

How these figures are worked out
We took the centre point of every live postcode in L14 from OS Code-Point Open and tested it against the Environment Agency’s Flood Map for Planning, as published in the flood-risk-zone dataset (version of 5 November 2026). A postcode counts once, whether it has one home or forty, and a postcode whose centre is just outside a zone still counts as Zone 1. Updated November 2026.
For one address, the free postcode check looks at the zones around the postcode, and the full report adds surface water, reservoirs, recorded floods and defences.
